.IROCESS OF INTRODUCING \VATER-INSOLUBLE OILS INTO EMULSIONS OI \VATER- SOLUBLE BODIES.

No Drawing.

To all whom it Hi (11 (OI'LC'FI'HI Be it known that l. JUTIN l'lENHY s'ittlll, a citizen of (treat Britain, residing' at La Garenne-Coloml'ies. France. ha 3 invented a certain new and useful improvement in Processes o't introducing \Vaterlnsoluble Oils into l lmulsions )r \Vater Soluble Bodies, of which the feilowing a specification.

It. is often desirable to bring ethereal oils into intimate combination with bodies soluble in 'Water, either on the score of economy or of other advm'itages accruing therefrom.

In practising the bleach-out process of color photography, it. would be of great, advantage to employ the ethereal oils. on aeeount, of their favorable properties as sen sitizers. in Combination with gelatin -and such like excellent, water-soluble mediums of support. Hitherto, however. this has not been practised on account. of the insolubih ity of these oils in water. I have 't'oun'd that, many-(rt these etliercal oils may be brotight, into intimate eombitnttion with get atin either in a state of solution or in the form of a very tine emulsion by mixing with water-soluble oils such as Turkey red oil in watery solution and drying the resulting mass preferably spread out in a thin layer.

It. is best to mix the ethereal oil first with Copies of this patent may be obtained for Specification of Letters Patent.

the water-soluble oil and then add to the gel tin solution or emulsion; but the watersoluble oil may be added tirst to the gelatin solution and the ethereal oi] afterward.

\Vhat I desire to secure by Letters leient is: I

1. The process tor the int roduetion oi water insoluble oils into emulsions or water soluble bodies, which consists in .imzorporatint: water insohrble oils and water soluble oils with the emulsion or water soluble body. The prot'ess for the illll'Ot'lut'tlMl oi \VtliQl insoluble oils into emulsions or water .soluble bodies. which consists in mixing the water insoluble oil with a wnter soluble oil. and incorporating the mixture in the emulsion or the aqueous solution of the solubie bodies.

3. The process for the introduetitm oi unteninsoluble oils into emulsions or water soluble bodies. which consists in mixing the water insoluble oil with n water soluble oil. incorporating the mixture in the emul ion or the aqueous so ution of the soluble bodies. and spreading the mass so obtained for the purpose of drying.
